Second, as the lubricant was ter adapted at its forward and rear ends to 5 dropped upon thewick on top of the saddle bear upon the journals 0 c of the drawingit was frequently, through almost innumerrolls and the former saddle at its forward end able causes, transferred to the surface of the to bear upon the journal d of the upper drawrolls, and by that means the serviceability of ing-rolls and at its rearward end upon the go the latter was seriously impaired. Again, back or upper side of the saddle b, as is usual I00 in the construction and arrangement of saddles, excepting as is hereinafter described as novel and peculiar.

edesignates the stirrup, arranged, as usual, to engage the saddle a and adapted at its lower end to receive the com monly-employed weighted lever.

Instead of forming chambers in the upper surfaces of the back saddle Z) and placing wicks in said chambers, as has heretofore been commonly done, in order to take up a lubricant and convey the same to the journals'of the top rolls I form a hole or aperture through the body of the saddle and thread or draw the lubricant-conveying wick through said aperture, so that it shall not only be substantially concealed from view, but be protected against dust or fiyings lodging therein to absorb the lubricantand befoul the parts and also so as to be protected against accidental. removal or against being accidentallypicked outin cleaning the machine. This is the essential part of my invention-that is, that I provide the body of the back saddle b with an aperture 1), extendinglongitudinally through it, so that the oil-conveying wick 7L may be protected from end to end against accidental displacement or against being wiped off or picked out in cleaning the machine, and all this notwithstanding the fact that at the ends of the wick, as at g g, they are made to project from the aperture to a slight extent into cavities m m and also notwithstanding the fact that oilholes are provided at some points, so that a lubricant poured into said holes may reach the body of the wicks intermediate of their ends and be taken up thereby to be conveyed in a regular and proper manner to the journals of the rolls.

In Fig. 6 I have shown the hole or aperture f, in which the wick is drawn, as kite or balloon shaped. This form, for several reasons, I may in some instances prefer to use, though I desire it to be expressly understood that my invention, in its broad sense, comprehends a back saddle in which the lubricant-s11 pplyin g wick is contained within a hole or aperture bored or formed through the body of the back saddle, so that the wick is not exposed to an extent rendering it liable to be picked out by mistake or wiped off or to have the lubricant contained therein liable of being conveyed to the surface of the top roll and a hole or aperture formed in the saddle for conveying a lubricant to the body of the wick at a point intermediatc'of its ends.

By my invention in addition to the advantages before mentioned I have ascertained that the lubricant absorbed by the wick is more evenly conveyed to the roller-journals, and,furthermorc,the lubricant lasts longer by reason of the fact that it is not wasted by being wiped off with dirt or conveyed too rapidly to the journals. Again, by my invention, in-

asmuch as the wick is not exposed on the upper sides of the saddles excepting to a slight extent, as the end may project through the aperture formed in the body of the saddle, as shown, there is little or no liability of draggin g or conveying the lubricant from the wick to the outer working surfaces is of the rollers, as is the case with back top-roll saddles as now commonly employed, it being well understood that if oil or other similar lubricant gets upon the surface of the rolls it interferes to a very serious degree with the serviceability of the latter, if it does not entirely destroy the same.

It is to be noted that the wick hole or bore extends through the body of the back saddle between the inner end walls of the cavities formed at the extremities of the saddle in the under side of the same. This is of obvious advantage both in the manufacture of the saddle and in the threading of the wick therethrough.

In Figs. 1 and 3 I have shown the forward saddle a as being capable of receiving a lubricant to be conveyed to the wick through the medium of achamber h back of the stirrup e, while in Figs. 2 and 41 have formed achainber i in front of the stirrup c and, as is represented in Fig.5, I form a recess or chamberj in the upper side of the saddle b, with oilholesj in the bottom of said chamber communicating with the wick in order to convey a lubricant to the latter. I however make no claim herein to the forward saddle or its structural characteristics.

Having thus explained the nature of the invention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, it is declared that what is claimed is 1. A back top-roll saddle provided with a hole or aperture extending longitudinally through its body part and opening at opposite ends into cavities at points in proximity to the bearings of the rollers upon which the saddle rests, and one or more oil-holes entering from above into the said longitudinal aperture intermediate the ends thereof, together with a wick occupying the longitudinal aperture and protruding from the ends thereof.

2. A back top-roll saddle having cavities in its under side at opposite ends and a longitndinal bore extending through the body of the saddle between the inner end walls of the cavities; together with awick occupying said bore with its ends protruding into the cavities, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 5th day of October, A. D. 1898.
